The equations ignore air resistance, which has a dramatic effect on objects falling an appreciable distance in air, causing them to quickly approach a terminal velocity. The effect of air resistance varies enormously depending on the size and geometry of the falling object—for example, the equations are hopelessly wrong for a feather, which ...
Airspeed is commonly given in knots (kn). Since 2010, the International Civil Aviation Organization (ICAO) recommends using kilometers per hour (km/h) for airspeed (and meters per second for wind speed on runways), but allows using the de facto standard of knots, and has no set date on when to stop.

Steady initial climb speed. The all engines operating take-off climb speed used to the point where acceleration to flap retraction speed is initiated. Should be attained by a gross height of 400 ft (120 m). [10] V A: Design maneuvering speed. This is the speed above which it is unwise to make full application of any single flight control (or ...
In aeronautics, the rate of climb (RoC) is an aircraft's vertical speed, that is the positive or negative rate of altitude change with respect to time. [1] In most ICAO member countries, even in otherwise metric countries, this is usually expressed in feet per minute (ft/min); elsewhere, it is commonly expressed in metres per second (m/s).
convert CAS to equivalent airspeed (EAS) by allowing for compressibility effects (not necessary at slow speed or low altitude); EAS is used by aircraft engineers and some very high-altitude flying aircraft such as the U-2 and the SR-71; convert EAS to true airspeed (TAS) by allowing for differences in density altitude.
1 inch per second is equivalent to: = 0.0254 metres per second (exactly) = 1 ⁄ 12 or 0.08 3 feet per second (exactly) = 5 ⁄ 88 or 0.056 81 miles per hour (exactly) = 0.09144 km·h −1 (exactly) 1 metre per second ≈ 39.370079 inches per second (approximately) 1 foot per second = 12 inches per second (exactly)
